Akarethrips iotus sp.n.

Female macroptera. Body largely yellow, anterior part of head light brown, mesothorax shaded brown, tube brown on distal four-fifths; antennal segments I–III yellow, IV–VIII dark brown; all legs yellow; major setae pale; fore wing weakly shaded.

With the character states indicated above; head with pair of setae on basal third ( Fig. 6 ), weak lines of sculpture present near posterior margin; postocular capitate; mouth-cone short and round.

Pronotum relatively large, with sculpture only near posterior margin; mesonotal lateral setae capitate; metanotum weakly reticulate, median setae pointed; fore femur slightly enlarged; fore tarsal tooth pointed, as long as tarsal width; fore sub-basal setae capitate, S2 and S3 closer to each other than to S1 ( Fig. 7 ).

Pelta weakly sculptured, campaniform sensilla present ( Fig. 9 ); tube with anal setae a little shorter than tube.

Measurements (holotype female in microns). Body length 1525. Head, length 160; width 135; postocular setae 50. Pronotum, length 150; width 210; major setae – am 35, aa 35, ml 50, epim 45, pa 55. Mesonotum lateral seta 25. Fore wing, length 625; sub-basal setae 35, 45, 40. Tergite IX, setae S1 60; S2 65; S3 70. Tube length 95; anal setae 90. Antennal segments III–VIII length, 50, 50, 45, 40, 35, 25.

Male macroptera. Very similar to female but darker and smaller; head and thorax brown, abdomen yellow, segment IX brown on posterior half; antennal segment III shaded brown in apical half; tergite IX setae S2 short and pointed; sternites IV–VI with median transverse band of reticulation, VII with similar band laterally, VIII without pore plate.

Measurements (paratype male in microns). Body length 1310. Head, length155; width 120; postocular setae 45. Pronotum, length 125; width 195; major setae – am 30, aa 30, ml 40, epimeral 40, pa 45. Tergite IX setae, S1 60; S2 20. Tube length 85; anal setae 85. Antennal segments III–VIII length, 40, 45, 40, 40, 30, 25.

Specimens studied. Holotype female, Peninsular Malaysia, Gombak , near Kuala Lumpur, beaten from Mikania scandens dead twigs, 7.x.1973 (LAM 1085), in The Natural History Museum, London.

Paratype: 1 male from same site as holotype, beaten from herbs and climbers, 29.ix.1973.

Comments. Nothing is known of the biology of this new species, based on two individuals that were collected separately although at the same site.
